You're basically going to overload your melee and turn yourself into a true enh shaman.

The lack of stormstrike is a bit appalling, but we'll make due with Follow Through instead.

My biggest concern with Thrall is how weak his Windfury feels, sure it increases move speed and attack speed, but with little punch.

Follow Through, Giant Killer, and Nexus Blades help immensely with that problem, and helps it even further utilize move speed boost.

We're doing the mass % based auto attack stacking.

Level 1
- Main Block:
Your main survival tool. You're going to be in their faces and you need some padding.
- Alt. Rabid Wolves:
Getting more Frostwolf Resilience stacks, can help you survive if you're landing them

Level 4
- Main Envenom:
Thrall's chase-down potential is a bit lacking without a gap closer. Finish them.
- Alt. Mana Tide:
Can be useful if you feel you're getting your mana drained like a hunter pre-cata.

Level 7
- Main Follow Through:
Combos really well with Windfury or a Feral Spirit. This is where the magic starts, and your autos start to drop health bars.
- Alt. Wind Shear:
Can help you get more Frostwolf Resilience stacks, or help keep you in the front line.

Level 10
- Main Sundering:
Awesome in teamfights, finishing someone off, or making a clean getaway.
- Alt. Earthquake:
Can help for you to stick on people like a ****ing magnet. Very good in teamfights, especially with a stacked melee team.

Level 13
- Main Giant Killer:
Here begins stage: 2 of your melee onslaught. You're going to be slamming a bigger hammer, now.
- Alt. Grace Of Air:
Another Frostwolf Resilience Stacker. A very good pick with Wind Shear if you're going for a more "on use" Windfury build.

Level 16
- Main Tempest Fury:
You've got your reason for the heavy-hand stacking, now. That third windstrike is going to tear healthbars. You'll be slamming nukes and it's going to be satisfying.
- Alt. Blood for Blood:
A good choice if the enemy team has a lot of escape abilities, or if you need a tank-buster.

Level 20
- Main Nexus Blades:
Your massive hammer auto attack stack is complete. You'll probably want to dive into teamfights and rip faces off, but I'd advise caution and try not to let your team down.
- Alt. Bolt of the Storm:
Again, good choice if the enemy team has a lot of escapes, combos well with Blood for Blood for an even better engage/follow up attack. Also combos well with Follow Through
